Why Lesson Planet?
Develop the concept that numbers from 11 to 19 are essentially a 10, plus more! The first two of the six story problems on this sheet are scaffolded with pictures. Learners compose and decompose numbers to answer how many 10s and how many 1s. Consider actually giving the children happy face stickers, pencils, football cards, rocks, buttons, and marbles so that they can demonstrate their understanding with manipulatives!
